PLOW.

Specification of Letters Patent.

Patented .Tune 15, 1909.

T 0 all whom it 'ma/y conccm:

.Be it known that I, JAMES RAP'HAEL Rossnrrnn, a citizen of the United States, residinp; at (Knoxville, in the county of KnoX and State of Tennessee, have invented certain new and useful Improvements in Plows; and I do hereby dcclare the following to be a full, clear, and exact description of the invention, such as Will enable others skilled in the a rt to which it appertains to make and Vuse the same.

This 'ir'i'vention relates to plows having a detachable landside, and .the object thereof is to prevent a plow from loosing its original gatheiy fi. e. the concave or inward curvo of the landside face of the plow which causes th iinplemcnt to holdto a straight line when at work. It is absolutelynecessary to presorvc this curvo in order to keep the plow in perfect Working` order, for if the landside face of'the plow becomes flat or slightly conveX, the plow Will no longer hold to a straight linel but Will tend to zigzag in the furrow and run out of theland. Loosing` this curve has been a serious fault of all plows having a detachable landside.V Thel landside is held to place by bolts, and When these bolts become looscned dirt is allowed to `get in between the parts and push out the landside, whereby the concave is lost and the plow will not do good work. To obviate this difficulty is the aim of my invention, which I accomplish by means as h creinafter described with reference to the accompanying` drawings and more particularly pointcd out in the claims'appended to this description.l

In said drawings, Which are to be taken as a part of this specification: Figure 1 is a side clevation, looking at the landside, of a plow enibodying .my invention. Fig. Zis an enlarged horizontal (section on line II-II of Fig. I. Figs. 3 and 4 are detail perspective views of the interfitted' parts of the plowstandard and landside.

' I have illustrated in the drawings a ploW of substantially the construction disclosed in my prior patents'Nos. 644,099 and 7 40,37 3, wherein the plowsharel and other operative parts are fitted to and secured upon a standard, frog or sad dle 2, which is shown attached to the foot of the beam-or standard 1 but may of course be a part of the standard itself. The landside 3 has its forward portion fitted in a lateral recess or depression 4 in the heel of the standard 2, and is fastened by the bolts 5 and 6. By the shape of said recess and 'interengaging` shoulders between the parts at '7,V as more fully explained in niy first mentioned patent, the landside is firmly fitted and the bolts are practically relieved of shearing strain.

As shown in Fig2, Where the line x is a straight line touching the plo'woint at y and the heel of the landside at zat ie concave of the landside face of the plow is in part produced by a slight angular disposition or lateral inclination of the landside Which splays outwardly from its front to its rear end. It is the function of my present improvement to maintain thevlandside in such osition, that is to prevent its front end from ateral displ'acement and keep it flush with the standard. This is effe'cted by an. interlooking connection between the front end of the landside and abutting part of the standard; a preferred means, as shown, consisting of a lug'S in the` sha e of the half-part of a round countersunk olt-head cast on the front wall of the recess 4, and a corres r ondingly-shaped socket or half-part of a role 9 on the front end of thelandside. When the landside is shoved forwardly into laee in the recess 4 of the standard, the beveled Wall of the hole 9 riding under that of the lug S first be moved rearwardly until the socket 9 is with'drawn from nder'the lug. Hence it Will be seen that even if the bolts should Work loose, the concave of the landside face of the plow would-neverthcless bc maintained, as the lug and socket Would prevent the forward. end of the landside from being pressed outward.

-In casting 'the lug 8 on the standard, and in order to get the patterns out of the sandmold, that portion of 'the mold *which forms the log is advisedly madeby means of a small pattern piece', correspeunding`v to the shape of the lug, which is set in a hole in the front end of the recess that takes the landeov rio

side, and, When the mold is opened, i's lifted out With a cope WherebjT the impression is left for the lug, as Will be"'understood by those familiar with the art of metal casting;

I donot intend to restrict myself to the specific construction shown, but reserve the right to an equivalent means that will .ac-

com lishI t e desired purpose, as for examp e a lug on the -end of the landside engamg in an undercut socket 4in the front Wa 1 of the recess4, fl

The term concave, as used herein, is not to be understood in a mathematical sense as denoting a surface which is strictly curved throughout, but signifies a surface which is concave in effect, as for example Where the concave is produced .by plain surfaces angularlv disposed. aving thus I claim as new and desire to secure by Let'- ters Patent is:

1. A plow having a detaehable landside and means for ,maintaining the concave bof the landside face'of the plow Which consists of 'an interlockingconnection between 'the front end of the landside 'and 'contiguouspart of the plow Where-by said front end of the landside is prevented from lateral displacement.

described my invention ivhat 2. A plow having a dathabie iandside, the plow-standard having a lateral reeess in Which the landside is fitted, and means preventing lateral displacement of the forward end of the landside Whereby to maintain the concave of the landside face of the plow, said the plow-standard having a lateral recoss in which the landside'isfitted, and means "preventing lateral displacement of the forward end lof the landside whereby lto maintain the 'concave of the landside face of the plow, said means'eonsisting. of a lug'substantially .like

the half part of a countersunk-bolt-head on the front wall of said recess and a corres ondingly shaped socket on the front end of the landside, the said lug being seated in the said socket.

In .testimony Whereof I' aiiix my signature, inpresence of two Witnesses.
